Alan Gouk compares Mondrian and Nicholson

“If one applies to the Nicholsons the same unscrutinising mode of vision, looking “through” that I suggested for the Mondrians, encouraging simultaneity of perception of the dispersed coloured planes, what tends to happen, precisely because the two-dimensional unity of the picture-plane is so convincingly maintained, is that the more strongly hued planes begin to present themselves in a sequence, first one, then an instant later another across the mediant, tertiary, spatially more luminous surfaces, in a sequential rhythm, one that is indeed, as Nicholson felt, akin to a musical experience, all this helped by the relatively small size of the pictures, so that one can take them in without head-movements.”
